In May I adopted Remy (age6) he had been with a local rescue for 3 years.My cat Ziggy had died 2 months before. He had been very sick for months. His illness was emotionally and financially draining. I made sure that before I adopted a cat he was healthy. I had been reassured that Remy was FIV/FeLV neg. Well , Remy seemed to be run down lately so I took him to a new vet ( I didn't feel old vet had given him a thorough exam originally) sure enough Remy has dental reabsorption and FIV.Truthfully I would not have adopted him had I known that. Now I love him and he is mine.Here is the problem. In Sept. I adopted a 10 month old cat- Desmond. Desmond is suddenly (just this week) really harassing Remy. Remy is a kind soul and now obviously feels threatened. Remy loves to play and wrestle so it isn't that Desmond is harassing him. How do I stop this? I am terrified that there will soon be serious fighting.I also have another cat Leo (*) he and Remy are very bonded and my vet says Remy has to be seperted from the other cats. Forever. I don't want to live that way. I would re-home Desmond but he is a little black cat and so has almost no chance at a new home. I will not bring him back to the shelter.Meantime I am so ticked at original vet. I asked him on the day I brought Remy home about his teeth. I was told Remy's teeth were fine unless "You are a purist" Remy always seemed kind of smelly and I couldn't bathe away the smell. His eyes were always runny (Lysine helps that) and he had a yeasty ear which that vet said was nothing that some cats "are just like that" Now I have a good vet but I seem to have a big problem.I am also mad at the rescue group. I got a letter from them when I adopted and I was told if I was worried about Remy's teeth they would pay for the work. I wrote back and told them the vet said his teeth were great. Never heard back. They won't pay for the dental now because it has been more than 1 month. Obviously they knew his mouth was bad.Any advice?
